Not on the seven, but repairing my aging motorbike fairings.

This stuffs amazing it's a white power and some evil smelling solvent. Just v the crack in the fairing with the dremel, fill the v with the powder and drip the solvent over it. I even repaired one of the mounting lugs just like the picture on the web site (basically replaced the half that was missing).

I'll be surprised if I don't find a use for it on the car too.

Looks pretty useful !
The moulding bar is a nice touch and it says you can repair fibreglass with it too

Must be good stuff at £1247 per Kg

£1247 per Kg ? I got a "shop kit" from ebay for £30 came with 250g of powder and 300ml of liquid.

Not the cheapest stuff but it does do what it says.
